I read this as part of /r/fantasy's book bingo challenge. I suggest you do not do the same.
In writing, there is often a saying that 'you should write what you know.' In this book, this was something taken to the extreme. You can tell that the author knows his stuff... in a very narrow window.
It seems that every structural engineer and their family, friends, and coworkers have been shilled this book, sometimes even by the author himself. This is the path where I received it. You're not 'one of them' until you have read it. Well, now I am a 'one of them,' and it was certainly... an experience.
Set in year million, humanity's only hope to avoid annihilation via asteroid (or meteor) is sending embryos into space to an Earth-like planet, where they will recolonize the universe or something like that. The book follows the third generation of embryos thawed (aka, the third thaw) and their planet-sprawling adventures.
Complaint #1: Despite there being 15 members of the third thaw, we only get into the headspace of 5 of them (and that's being generous). Viewpoint is very erratic and shifts mid-paragraph, making it difficult for the reader to understand what is going on. A simple fix for this is focusing on a character each chapter, even if it just was the five characters we only hear from. It maintains the diversity of viewpoints but makes it understandable and manageable. Additionally, this could be spread out to the 15 members of the Thaw, because it really felt that while I got to know the 5 viewpoint characters well, I could honestly not tell you the other 10 people's names.
Complaint #2: Sensitive topics, including race, religion, and sex. These topics are not handled well at all. The book could have, at the bare minimum, included a sensitivity reader. Yes, it's cool that there are PoCs in the book but... like, if you're going to include the hard-hitting topics about race and have 14-y/os discuss it, you can have it be more than a paragraph. Or at least have internal monologuing.
Complaint #3: (On the topic of sex): IF YOU ARE SENDING EMBRYOS WITH THE EXPLICIT PURPOSE OF RECOLONIZING HUMANITY, AT LEAST PUT SEX ED IN THEIR CURRICULUM. Yes, teens will experiment. But you should at LEAST give them a heads-up to, oh, idk, PREPARE them if A goes in B, C might come out.
And like, sex and having kids SHOULD be a choice. You should not be responsible for repopulating humanity. Consent, y'all.
Don't get me started on the spheres of influence. It gets better, but not by much.
Complaint #4: In some stories, a civilization looks oddly like some, say, 15th-century analogue with slightly modified names and places. Hanson just throws this out the window and says, yes, totally, the dinos that you see are the actual dinos that Earth had blah-billion years ago. At least use your imagination!
Complaint #5: Infodumps. There are a lot of them. They probably make up 25% of the novel. And before you think they're just in the first ~20%, no, there was an infodump in the last part of the book, because we needed to know the in-depth history of how the German and English languages diverged.
Complaint #6: Some books, like the Terra Ignota series, make language integration cool. You can tell when another person is speaking another language but it doesn't ruin immersion. Well, if you want to be immersed, go pass a German 101 class, because the last third of the novel, there will be dialogue in German. Yes, thankfully, it is translated into English at the end of the sentence, but there's nothing quite like reading dialogue and having zero comprehension.
Complaint #7: There is a whole plot thread nixed. At the beginning of the story, we get a viewpoint character of a modern guy living and after his chapter, he kind of just never really appears, except in the VR mode. You would think that following the political (and world) drama of a potential meteor/asteroid striking would make for good reading. (Check out Ken Liu's "Mono no Aware" for this). Unfortunately, this never happens.
Complaint #8: Every SF fan's favorite "A" world: allegory. (Sorry ansible fans, better luck next time!)
New Eden. Adam. HMMMMMM.
German dude. Has an army of robots under his control. HMMMMMMM.
(Female) pianist who believes in a higher power. (Male) engineer who believes in the power of science and reason. HMMMMMMM.
I'm tired from complaining. If I had more time, I could probably wring it out more (robots, pacing, and other things come to my mind). But I'm tired of complaining and you're probably tired of me complaning. So, some of the decent parts.
The book isn't all awful. It has a plot, although pacing is an issue. The viewpoint characters are defined and not 2D. While there are spelling and grammar issues, they are few and far between and don't detract from the overall reading experience. It's short compared to the usual chonk fare, coming in at around 300 pages. And it includes a bibliography, so all you Peter Watts fans will feel at home.
If you think this is up your alley, this will qualify you for the AI square, local author for Illinois and Colorado (US), Ocean, and possibly self-pubbed. It's either that or an indie publisher,and I'm not bothering to do the research.
